The trend reportedly began on Facebook and soon caught up across social media platforms.

Halfway into January 2019, there are already two major social media trends. One is the picture of an egg that has more Instagram likes than billionaire reality TV star Kylie Jenner. And the other is the first social media challenge of the year: The “ten year challenge”.

Essentially, the challenge is to post pictures of what you look like now, compared to a photo from 10 years. It is unclear how and where this challenge began, but it has driven people down memory lane

But while the initial posts were full of nostalgia, or cringing at awkward photos from 10 years ago, others users online quickly began adding humour or more pointed posts.
